"It's hard to get the photos your friends have taken of you, and everyone always insists on taking that same group shot with multiple phones to ensure they get a copy," product manager Will Ruben posted in the blog.

For instance, when you go to a wedding, there will be many people taking photos throughout the day. You can quickly share your photos with the friends who are in them and get photos that your are in back.

You can also create groups in the Moments app that will sync photos with friends. The app uses facial recognition technology to group photos based on the friends who are in them, which is similar to the tagging used in the Facebook.
